Columbia River Gorge, involving many rock cuts ranging from 10 to 50 feet deep, with one as deep as 190 feet. Earth fills were up to 50 feet high, and some earth cuts exceeded 350 feet in depth. The project amounted to $3, 340, 000, and also involved four small bridges, two each for highway and railroad, several shoo-flies and a station grounds. Scheduled service was maintained on the railroad during the entire project. An Industrial Highway in British Columbia for the Argonaut Mining Company in the amount of $800,000. Electrolytic Copper Refinery: Serving as both engineer and contractor, Utah performed the planning, procurement of materials and construction of this large refinery for the Kennecott Copper Company at Garfield, Utah, and coordinated the work of the various specialty contractors.. The cost of the project was $17,000,000. Carbon Plant Additions in Texas for the Atlas Powder Company in the amount of $655,500. Argonaut Mines and Magnetic Concentrator: In early 1951 the existing world crisis caused a severe shortage of available iron ore for manufacture into the strategic steel end products. The Argonaut Mining Co. Ltd. was formed then as a wholly owned subsidiary of Utah Construction Company for the purpose of developing known ore deposits in the Province of British Columbia, Canada, and prospecting for new deposits to help alleviate the world iron ore shortage. Extensive diamond core drilling and magnatometer surveys were made to determine the extent of the primary ore body. Since commencement of operations a continual program of exploration has been carried on to discover and measure new ore bodies. A major logging and land clearing operation had to be carried out as a portion of the development program. Main haul roads, pit access roads and stripping of overburden from the deposits constituted months of intensive work before actual mining of the iron ore could begin. Another phase of the development program required the design, engineering and construction of a complete iron ore crushing, screening, separation, blending and storage facility with a capacity of more than 60, 000 long tons of concentrates per month. Conveyors, reclaiming tunnels, wet and dry magnetic separators are among the major components of this plant. Excepting impossible weather conditions and improvement work, the plant has been in continuous operation since its construction. p/6- Radar Station Facilities in Washington for the U. S. Corps of Engineers in the amount of $972,000.
